The terminus at Tokyo Station is located underground, some distance to the south of the main station complex approximately halfway to Yūrakuchō Station. This means transferring between other lines at Tokyo Station can take between 15 and 20 minutes.
The name "Keiyō" is derived from the second character of the names of the locations linked by the line, Tokyo (東京) and Chiba (千葉). It should not be confused with the Keiō Line, a privately operated commuter line in western Tokyo.
